I know my sandisk extreme pro cards have never exhibited any issues with the other cameras. I have ordered a different sd card (samsung pro+ 64gb) to test if I will get any issue...
Cards are made in batches using memory and controllers made in batches. Its entirely possible to produce a marginal batch of cards. If a marginal card meets a camera that is using a faster clock speed, for example, then occasional glitches can happen. The fact that the card works on your other camera is no guarantee that it will work on a newer one that may push a card harder.
This type of issue can be very difficult to detect, because another batch may be a little faster and never have a issue. Not all cards of the same part number are the same, there is variance.
